Description

Technical Field

[0001] The present invention belongs to the technical field of water quality detection, and particularly relates to a water quality and water level detection device. Background Art

[0002] Water quality and water level detection are important links in water resource management and environmental protection. They each involve different detection methods and equipment. Water quality detection mainly focuses on the physical, chemical, and biological characteristics of water bodies to evaluate the quality and suitability of water bodies. Water quality detection methods usually include on-site rapid detection and laboratory analysis. On-site rapid detection uses portable detection instruments to quickly obtain preliminary results; while laboratory analysis uses more precise instruments and methods to obtain more accurate data.

[0003] In a Chinese patent with the publication number CN117968794A, a mobile reservoir water level measurer is mentioned, including a bottom plate. A box body is fixedly installed on the top of the bottom plate. An adjusting mechanism is fixedly installed at the upper end inside the box body, and a box door is fixedly installed on the front of the adjusting mechanism; by moving the pressure sensor downward, the relationship between water pressure and water depth can be utilized. When the water level in the reservoir changes, the water pressure will also change accordingly. The pressure sensor indirectly measures the water level by measuring the water pressure, so that during the measurement of the device, no matter how the rope body is inclined, it will not affect the water pressure at different depths of the water body, making the measurement of this device more accurate. At the same time, during this process, as the connecting rope moves downward, the water quality sensor and the camera can be driven to move inside the water body. At this time, the water quality sensor detects the water quality of waters at different water levels, enabling this device to comprehensively detect the water quality inside the reservoir.

[0004] For the water level measurer in the above comparative patent, it is generally used in conjunction with a water pipe for sampling. Solid particles are likely to enter the inside of the water pipe, causing the measurer to be blocked. And due to the rapid retraction of the pipe, water sources are likely to remain inside the pipe, causing the sewage inside the pipe to ferment, producing odors and corroding the water pipe. At the same time, the device is placed on the ground with a relatively low height, and the staff needs to squat for operation, which brings inconvenience to the sampling and detection work. Summary of the Invention

[0005] The purpose of the present invention is to provide a water quality and water level detection device to solve the problems in the above background art, that is, the water level measurer is generally used in conjunction with a water pipe for sampling.
